the SHAPE of DNA
What is a helix?
The organelle where transcription occurs.
What is the nucleus?
The organelle where translation takes place.
What is cytoplasm/ribosome?
This type of mutation occurs when a single nucleotide is swapped for another, such as an "A" being replaced by a "G."
Question: What is a Point Mutation (or Substitution)?
This is the name of the building blocks of DNA (it contains three molecules).
What is a nucleotide?
The molecule produced in transcription.
What is mRNA?
The product of translation (what translation makes)
What is a protein? (polypeptide)
In Sickle Cell Anemia, a single substitution mutation causes hemoglobin to clump; this demonstrates the biological rule that a protein's ability to carry oxygen is lost when there is a change to this.
What is its shape (or structure)?
These two things make up the "backbone" of DNA.
What is phosphate and sugar (deoxyribose)?
These are the 3 types of RNA
What is mRNA, tRNA, rRNA?
A 3 letter sequence of nitrogen bases that codes for an amino acids
What is a CODON?
This sequence of amino acids is made when this gene is expressed:
TAC CCC AGT CGT
What is Met — Gly — Ser — Ala?
The enzyme that opens the strand of DNA.
what is helicase?
If the DNA sequence is GCAATC, this is the mRNA sequence.
What is CGUUAG?
The name for the sets of 3 nucleotides on mRNA.
What is codon?
The reason Himalayan rabbit's fur grows back dark in colder weather
What is the melanin gene is only turned on or expressed when the temperature is cold?
the enzyme that adds base pairs to the template strand during replication.
what is DNA Polymerase?
This type of RNA brings amino acids to ribosome
What is tRNA?
This determines the amino acids in a protein.
What is the specific sequence of nitrogen bases?
This "shift" happens when a nucleotide is inserted or deleted, changing every single amino acid that follows in the chain.
What is a frameshift mutation? (Insertion or deletion)
